Hi
When we use a double flip-flop for dealing with metastability in CDC, although the second one helps to come out of metastability state, it doesnt necessarily give the correct output value right? for e.g., say the first flip flop went into a metastability state while trying to latch a "1" ... a "0" can be seen at the output of the second flip flop after the metastability state is resolved right? If this is correct then how is this handled? to make sure a wrong value is not propogated?
Thanks
